A grouping container for {@link Ext.form.Checkbox} controls.

-var myCheckboxGroup = new Ext.form.CheckboxGroup({
- id:'myGroup',
- xtype: 'checkboxgroup',
- fieldLabel: 'Single Column',
- itemCls: 'x-check-group-alt',
- // Put all controls in a single column with width 100%
- columns: 1,
- items: [
- {boxLabel: 'Item 1', name: 'cb-col-1'},
- {boxLabel: 'Item 2', name: 'cb-col-2', checked: true},
- {boxLabel: 'Item 3', name: 'cb-col-3'}
- ]
-});
- *
- * @constructor
- * Creates a new CheckboxGroup
- * @param {Object} config Configuration options
- * @xtype checkboxgroup

The controls will be rendered one per column on one row and the width
- * of each column will be evenly distributed based on the width of the overall field container. This is the default.
- * - Number :
If you specific a number (e.g., 3) that number of columns will be
- * created and the contained controls will be automatically distributed based on the value of {@link #vertical}.
- * - Array : Object
You can also specify an array of column widths, mixing integer
- * (fixed width) and float (percentage width) values as needed (e.g., [100, .25, .75]). Any integer values will
- * be rendered first, then any float values will be calculated as a percentage of the remaining space. Float
- * values do not have to add up to 1 (100%) although if you want the controls to take up the entire field
- * container you should do so.
